"""The bidirectional mapping library for Python.

----

bidict by example:

.. code-block:: python

   >>> from bidict import bidict
   >>> element_by_symbol = bidict({'H': 'hydrogen'})
   >>> element_by_symbol['H']
   'hydrogen'
   >>> element_by_symbol.inverse['hydrogen']
   'H'


Please see https://github.com/jab/bidict for the most up-to-date code and
